Host vs. pathogen evolutionary arms race: Effects of exposure history on individual response to a genetically diverse pathogen

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionThroughout their range, bighorn sheep (Ovis canadensis) populations have seen significant disease-associated declines. Unfortunately, understanding of the underlying epidemiological processes driving the disease dynamics in this species has ...

REPRODUCTIVE STRATEGIES OF DESERT BIGHORN SHEEP [PDF]

open access: yesJournal of Mammalogy, 2000
We examined temporal breeding patterns of bighorn sheep (Ovis canadensis) in the Peninsular Ranges of California to determine the degree of seasonality and identify potential selection for seasonal breeding in this low-latitude desert environment.

Experimental Transmission of Bighorn Sheep Sinus Tumors to Bighorn Sheep (Ovis canadensis canadensis) and Domestic Sheep [PDF]

open access: yesVeterinary Pathology, 2016
Bighorn sheep sinus tumors are a recently described disease affecting the paranasal sinuses of Rocky Mountain bighorn sheep ( Ovis canadensis canadensis). Several features of this disease suggest an infectious cause, although a specific etiologic agent has not been identified.

Bighorn sheep gut microbiomes associate with genetic and spatial structure across a metapopulation. [PDF]

open access: yesSci Rep, 2020
Studies in laboratory animals demonstrate important relationships between environment, host traits, and microbiome composition. However, host-microbiome relationships in natural systems are understudied.

Evaluating wildlife translocations using genomics: A bighorn sheep case study. [PDF]

open access: yesEcol Evol, 2020
Wildlife restoration often involves translocation efforts to reintroduce species and supplement small, fragmented populations. We examined the genomic consequences of bighorn sheep (Ovis canadensis) translocations and population isolation to enhance ...

Removal of chronic Mycoplasma ovipneumoniae carrier ewes eliminates pneumonia in a bighorn sheep population. [PDF]

open access: yesEcol Evol, 2020
Chronic pathogen carriage is one mechanism that allows diseases to persist in populations. We hypothesized that persistent or recurrent pneumonia in bighorn sheep (Ovis canadensis) populations may be caused by chronic carriers of Mycoplasma ovipneumoniae

The Bighorn Habitat Assessment Tool: A Method to Quantify Conservation Value on Landscapes Impacted by Mining

open access: yesLand, 2022
We present a methodology to assess the conservation value of mitigation lands for desert bighorn sheep (Ovis canadensis nelsoni) within landscapes impacted by historic and ongoing industrial uses.
